ABSTRACT

A lens for eyeglasses is provided with two or more optical zones on the lens body having different optical properties that enhance visualization of different scenes, including target objects within the scenes, that are associated with a specific recreational activity such as golf, hunting, or fishing. A first optical zone in an upper portion of the lens can be provided with pre-defined focus distance, transmission percentage, and/or transmission spectrum parameters for enhanced visualization of distant scenes associated with the specific recreational activity. A second optical zone in a lower or outer portion of the lens can be provided with different pre-defined focus distance, transmission percentage, and/or transmission spectrum parameters for enhanced visualization of close-in scenes associated with the specific recreational activity.

This is a continuation-in-part of co-pending U.S. patent applicationSer. No. 09/469,916 filed Dec. 22, 1999 now U.S. Pat. No. 6,250,759entitled “Eyeglass Lens With Multiple Optical Zones Having VaryingOptical Properties for Enhanced Visualization of Different Scenes inOutdoor Recreational Activities.”

BACKGROUND OF THE INVENTION

The present invention relates generally to wearable optics for outdoorsporting and recreational activities. More particularly, this inventionrelates to eyeglass lenses having optical properties optimized foroutdoor sporting and recreational activities.

In many sporting or recreational activities, such as golfing, fishing,or hunting, the participant needs to visualize different scenes,including target objects within such scenes, that are typicallyassociated with that activity. The color spectra and ambient lightingassociated with different target objects and scenes in recreationalactivities can vary, whereby a light filtering lens on an eyeglassshould provide preferential viewing for certain color spectra undercertain light intensity conditions to accommodate a specific scenetypically encountered while participating in the activity. Using golf asan example, a scene whereby the shapes and undulations of a greenputting surface being studied while preparing to putt would requiredifferent filtering properties for the lens as compared to watching awhite ball flying through the air against a bright sky background.Although sunglasses exist that provide a variation in total lighttransmittance from a top portion of the lens to the bottom portion, suchprior art lenses are often configured as standard neutral densityfilters with UV protection. They do not provide varying opticalproperties that provide preferential viewing to the wearer of thedifferent color spectra associated with different scenes.

Similarly, these different target objects or scenes often exist atdistances that vary between scenes or objects in a relatively consistentmanner. For example, during a round of golf, the golfer will often haveto locate a target green and flag stick at distances from 200-350 yardsaway. During that same round, the same golfer will be putting afterinspecting the shape and topology of a green from a distance of a fewyards. If the golfer wears glasses, the focus distances for each of therepetitive scenes are different. However, there are no eyeglassesavailable that are optimized for focusing at these distances.Conventional bifocals are intended to provide near focus distance forreading a book, not for reading a green or standing over a golf ball.

In other recreational activities such as fishing, having a lens thatincorporates different optical zones having different polarizationproperties can also be beneficial.

What is needed, then, is an eyeglass lens that provides a visualperception to the wearer that can vary depending on: (1) the distancebetween the wearer and the object being viewed; (2) the color spectra ofthe viewed objects and related foreground and background scenes; (3) theambient lighting conditions; and/or light polarization.

SUMMARY OF THE INVENTION

The novel eyeglass lens of this invention overcomes the deficiencies ofthe prior art by providing a lens body that includes one or more opticalzones having one or more optical properties optimized for use inspecific sporting and/or outdoor activities. The different optical zonesare positioned within or on the body of the lens such that changes inorientation of the head, or a change in position or size of the pupil ofthe wearer's eye with respect to the lens and different scenes(including target objects) can vary the optical properties of the lensas perceived by the wearer, including focus distance, total visiblelight transmittance, visible light transmission spectrum, and/orpolarization.

In one embodiment of the invention, an eyeglass lens has a lens bodywith a first optical zone positioned in an upper portion of the lensbody, adjacent to a second optical zone positioned in a lower portion ofthe lens body. The first optical zone has a first focus property thatallows the wearer to preferentially view a second typical distant sceneassociated with golf, such as a locating the green and flagstick priorto driving or hitting a long iron off the fairway. The second opticalzone has a second focus property that allows the wearer topreferentially view a first typical close-in scene associated with aspecific recreational activity, such as observing the shapes and curvesof a golf green while putting. When the user (i.e., a golfer) ispreparing to drive, he typically will rotate his eyes upward to lookdown the fairway towards the target area. This eye movement will orientthe pupil of the eye so that most of the light reflected from thedistant target scene will pass through the upper or first optical zone.When putting or preparing to putt, or when addressing the ball to drive,the golfer will typically re-position the pupil of the eye downward sothat a greater percentage of the light reflected from the close-in scenewill pass through the lower, second optical zone. This will allow thegolfer to more precisely focus on objects and backgrounds in such aclose-in scene.

Further, the first and second optical zones can also have differentcolor filtering properties, i.e., different visible light transmissionspectra. The transmission spectra for the first optical zone can beoptimized so that a white golf ball in flight against a brightly lit skybackground is easier to see. The color filter property of the secondoptical zone can be optimized so that changes in the shape or slope ofthe putting green when viewed from a close in location and under lowerintensity light are more easily observed. The differences in colorfilter properties between the first and second filter zones thus caninclude variations in filter spectra as well as variations in totallight transmittance through that portion of the lens. Accordingly, asthe golfer's eyes change orientation as they are rotated up and downwith respect to the position of the lens, the arrangement of the firstand second optical zones provides both a focus property and a colorfilter property that are optimized for different scenes, includingspecific objects, backgrounds, and foregrounds.

The different optical zones in the lens can be arranged in a typicalbifocal fashion, with an abrupt line or gradual transition between anupper and a lower zone. Alternatively, the second optical zone can be anoval or circle positioned in a specific location within the lens body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a first embodiment of an eyeglass lens 10 includesa conventionally shaped lens body 15 having a first optical zone 11located in an upper portion of the lens body 15. The first optical zone11 is provided with one or more optical properties to allow a wearer ofthe lens 10 to preferentially view a first typical scene (includingobjects, backgrounds, and/or foregrounds) associated with a specificoutdoor recreational activity, such as golf, hunting, or fishing. Thus,the first optical zone 11 can be clear or can be treated with a dye orinterference coating to provide desired parameters for transmissionpercentage and transmission spectrum properties for light at variousvisible wavelengths. Similarly, the first optical zone 11 can bemanufactured in a conventional manner to provide ideal focus at adistance range associated with the first typical scene. For example, thefirst optical zone 11 can provide optimum focus for targeting aflagstick on a golf green located 200 yards from the wearer, and canprovide color light filtering that provides preferential viewing of awhite golf ball against a bright sky background, as shown in FIG. 7.

Located immediately below the first optical zone 11 is a second opticalzone 12 that provides preferential viewing of a second typical sceneassociated with the same recreational activity. For example, the secondoptical zone 12 can be manufactured in a conventional manner to provideoptimum focusing at short range, such as the distance to a golf ballduring address for putting or driving. The second optical zone 12 isalso provided with different parameters for transmission percentage andtransmission spectrum properties to transmit a greater percentage of thetotal visible light as compared to the first optical zone 11, and forfiltering certain visible wavelengths, as shown in FIG. 4, topreferentially view the shapes and undulations of a putting green.Accordingly, as the wearer of the eyeglasses equipped with the lens 10rotates the pupils of his eyes upward and downward to observe thedifferent scenes typically encountered during a specific recreationalactivity, the pupils of the wearer's eyes are visually aligned with thefirst or second optical zone that provides enhanced visualization of twoor more different scenes associated with that activity.

FIGS. 1, 4, and 7 illustrate an embodiment of the lens of this inventionthat is adapted for enhanced visualization of different scenesassociated with golf. The first optical zone 11 is located in the upperportion of the lens body 15, corresponding to the portion used fordistant vision. As shown in FIG. 7, the transmission percentage andtransmission spectrum properties for the first optical zone 11approximately define a neutral density sunglass filter, gray in color,and having a total light transmission percentage that is substantiallyless than 100% and approximately constant over the visible wavelengths.Preferably, the transmission percentage decreases substantially as shownin FIG. 7 for light having wavelengths less than 400 nm, to provide UVprotection. The second optical zone 12 is located in a lower portion ofthe lens body 15, corresponding to the portion of the lens body 15through which closer scenes are viewed, particularly when the golfer islooking downward when studying a green or striking the ball. Theparameters for the transmission percentage and transmission spectrumproperties in the second optical zone 12 are selected to provideenhanced visualization of the shapes and contours of a green puttingsurface. As shown in FIG. 4, an amber (or cinnamon) tinted sunglassfilter can provide this effect. Thus, the first (upper) optical zone 11with a neutral density filter provides an excellent sunglass functionwith enhanced visualization of a white golf ball against a blue or agray sky. Also, by using a neutral density filter, changes in distanceperception are minimized, which can occur when using colored filters.The amber tinted filter forming the second optical zone 12 at the bottomof the lens body 15 comes primarily into use when the golfer is lookingdownward at the green for putting. An amber tinted filter increasesperception of the curves and contours of the green or putting surface.Optionally, the parameters for the focus distance property can be variedin a step transition between the first and second optical zones 11 and12, corresponding to the typical distances from the golfer to thebackgrounds and objects associated with the different golfing scenes.

A lens optimized for use in hunting glasses is shown in FIGS. 1, 5, and7. Again, the first optical zone 11 in the upper portion of the lensbody 15 provides a neutral density (approximately gray) filter (FIG. 7),and functions as a conventional sunglass without tinting of thebackground that can alter distance perception. Proper distanceperception is important in hunting when aiming a gun or bow at distantobjects. The second optical zone 12 in a lower portion of the lens body15 is provided with transmission percentage and transmission spectrumproperty parameters that enhance visual perception of red coloredobjects against different backgrounds. A lavender tinted filter havingthe transmission spectrum graphed in FIG. 5 can provide thisenhancement. The transmission percentage increases to a relatively highlevel for light having wavelengths between 650 and 710 nm, thewavelengths that correspond to red colors. The filter in the secondoptical zone 12 attenuates orange, yellow and green wavelengths butprovides a transmission peak in the blue region as shown in FIG. 7. Thecombination of red and blue tints creates a lavender tint as perceivedby the user, but wavelengths corresponding to red are transmitted, andstand out against the lavender background. Such a combination of opticalproperties is useful in tracking a wounded animal, in that while lookingdownward (through the second optical zone 12 in the lower portion of thelens body 15) blood drops are more clearly discerned. Again, the firstand second optical zones 11 and 12 can be provided with different focusdistance parameters, for focusing on objects at longer and shorterdistances respectively.

Yet another embodiment of the lens 10 is shown in FIGS. 1, 6, and 7, forenhanced visualization of different scenes encountered while fishing.The first optical zone 11 in the upper portion of the lens body 15 hasneutral density (gray) transmission percentage and transmission spectrumparameters shown in FIG. 7 or is provided with another color tint tocreate a useful sunglass effect when viewing objects at a distance.Optionally, the first optical zone 11 is not polarized so thatreflections from wave tops on the surface of the water being fished arenot diminished. This can be important when the user is looking forripples and surface reflections that may indicate the presence ofschools of fish below the surface. The second optical zone 12 in thelower portion of the lens body 15 provides different optical propertyparameters that enhance visualization of objects at short range andbeneath the water. This enables the fisherman to better “see” the fishor other submerged objects. A filter with an orange tint, with visiblelight transmission percentages and spectrum parameters such as thatshown in FIG. 6 enhances the visualization of objects submerged inwater. Also, the second optical zone 12 can be conventionally polarizedwith a polarization orientation that will reduce surface reflections andenable the fisherman to see objects beneath the surface of water atclose range.

FIG. 2 shows an embodiment of the lens 10 of this invention in whichthere is gradual transition in parameters associated with one or moreoptical properties, rather than a step or line transition as shown inFIG. 1. For example, the lens 10 shown in FIG. 2 can have a transmissionpercentage of total visible light that gradually increases from the topto the bottom of the lens body 15, with a corresponding gradual changein color tint, such as from a neutral density filter as in FIG. 7 to anamber tinted filter as shown in FIG. 4. Thus, a lens 10 of thisinvention with a gradual transition as shown in FIG. 2 essentiallydefines multiple optical zones. A similar effect can be provided in anembodiment having three or more adjacent optical zones with line or steptransitions in optical property parameters between them.

FIG. 3 illustrates yet another embodiment of the lens 10 in which secondoptical zone 12 is smaller as compared to the first optical zone 11 thatsurrounds it and is positioned in a lower, inside corner of the lensbody 15. Of course, the different optical zones can be sized, shaped,and positioned on the lens body 15 in a variety of ways not illustratedhere, for purposes of providing enhanced visualization of specificscenes associated with specific recreational activities.

As mentioned above, one of the optical properties having parameters thatcan be changed between optical zones for enhanced visualization ofcertain scenes (including target objects within the scenes) associatedwith a specific recreational activity is focus distance. In some cases,it may be beneficial to optimize the focus distance of each optical zoneto correspond to the needs of a particular wearer in addition to therequirements of the specific scenes. For example, magnification can beprovided in one or more optical zones.

FIG. 8 illustrates yet another embodiment of the lens 10 in which thefirst optical zone 11 is positioned in a central region of the lens body15, with second optical zones 12 a and 12 b positioned along the leftand right outer margins of the lens body 15. The first optical zone 11is provided with a tint density that is transmits a higher percentage oflight as compared to the more darkly tinted second optical zones 12 aand 12 b. This decreases the average transmission of visible light onthe left and right portions of the lens 10 as compared to the centralregion. In activities such as golf, there are situations and sceneswhere directing the eyes forward to the center of the scene whilereducing peripheral distractions would be beneficial. Conventionally, aparticipant in such an activity might cup his or her hands around theface, shielding the eyes from light arriving peripherally. Thisembodiment of the lens 10 accomplishes the same result in a morecontrolled manner.

A similar result can be achieved as shown in the horizontal optical zonearrangement of FIG. 9, showing a pair of lens bodies 15 where the firstoptical zone 11 occupies the central and inner portions of the lens body15, with a second optical zone 12 on the respective outer portions ofthe lens body. Note that the horizontally arranged optical zones asshown in FIGS. 8 and 9 can also be provided with other opticalparameters that vary from the first to second optical zones 11 and 12 aand 12 b, such as tint color, focus, or polarization. In fact, the firstoptical zones 11 can be clear with tinting only of the second opticalzones 12. Also, the horizontally arranged optical zones 11, 12 a and 12b, can be combined with the vertically aligned zones described above.

In another variation of the embodiments of the lens 10 described above,viewing of scenes associated with certain recreational activities suchas golf, fishing, and hunting can also be enhanced where the firstoptical zone 11 in the lens body 15 is provided with a blue or blue-graytint rather than a simple neutral density filter (gray tint). Similarly,for activities such as golf or fishing, the second optical zone 12 canenhance visualization of certain scenes if the lens is provided with anorange, yellow, or red tint. Thus, a lens manufactured in accordancewith the present invention will have a first optical zone 11 having apercentage of light transmission that is approximately constant withwavelength (corresponding to a gray tint) or will transmit a higheraverage percentage of the shorter wavelength visible light(corresponding to a blue or blue-gray tint). The second optical zone 12,by comparison, will transmit a higher average percentage of the longerwavelength visible light (corresponding to an amber, orange, yellow, orred tint).

In yet another embodiment of the lens 10 that is useful for ski glassesor goggles, the first optical zone 11 located on the upper portion ofthe lens/goggle body 15 is tinted gray, blue or blue-gray and the secondoptical zone 12 in the lower portion of the lens/goggle body 15 istinted amber, vermilion or orange. The vermilion tinted second (lower)optical zone 12 aids in the visualization of the contours of snow on theground that is viewed at close range while the neutral or blue tintedfirst (upper) optical zone 11 is preferred for distance viewing.

Those of skill in the art will recognize that lenses manufactured inaccordance with the objects of this invention can include standardprotection against UV light, by substantially reducing the percentage oflight transmitted at wavelengths known to cause UV damage, such aswavelengths that are shorter than visible blue light.

Thus, although there have been described particular embodiments of thepresent invention of a new and useful Eyeglass Lens With MultipleOptical Zones Having Varying Optical Properties for EnhancedVisualization of Different Scenes in Outdoor Recreational Activities, itis not intended that such references be construed as limitations uponthe scope of this invention except as set forth in the following claims.
